Lactic acid bacteria (LAB) are traditional dairy strains which have a long history of safe use. They are a kind of food-grade microorganisms that can be used in industry to produce lots of food and drink, such as yoghourt. In the last two decades the physiology and genetics of these bacteria have been thoroughly studied. Because of their genetic accessibility and easy to handle, LAB, in addition to their traditional applications, have been extensively developed and used for the expression of heterologous genes. So they have an important foreground in agricultural, medical and many other fields. People have developed a series of food-grade gene expression systems of LAB. LAB, especially their model strain Lactococcus lactis and their most useful food-grade induced expression system--nisin controlled gene expression system NICE and its food-grade inducer nisin, food-grade host, expressing vectors and applications in expressing heterologous proteins of NICE will be introduced.

Objective To compare the effects of different spleen-strengthening recipes on water-electrolyte metabolism and water transport in rat model of spleen-deficiency syndrome. Methods The male Wistar rats were randomly assigned into the normal group and spleen-deficiency model group. The rat model of spleen-deficiency was established by overstrain plus disordered diet method. On the 15th modeling day, the model rats were randomly assigned into model group , Buzhong Yiqi Tang(BYT) group, Si Junzi Tang(SJT) group, Shenling Baizhu San(SBS) group, and the rats except for the model group were treated with gastric gavage of the corresponding medicine in the dosage of 4.05 g·kg-1·d-1. Rats of normal group and model group were given equal volume of normal saline. The medication lasted for 14 days. On the 29th experimental day, we detected serum Na+ and K+, plasma antidiuretic hormone(ADH) and aldosterone(ALD), aquaporin 3(AQP3) in the small intestine and colon, and renal AQP2. Results Compared with the normal group, plasma ADH and ALD levels, serum Na+ level, renal AQP2 content in the model rats were increased significantly, serum K+ and AQP3 content of small intestine and colon mucosa was decreased significantly(P<0.01). Compared with the model group, plasma ADH and ALD levels, serum Na+ level, renal AQP2 content in the three medication groups were decreased significantly, serum K+level and AQP3 in the small intestine and descending colon mucosa was increased significantly(P<0.05 or P<0.01). Of the three medication groups, SBS group had lower ADH, ALD, Na+levels, and higher serum K+level and AQP3 in the small intestine and descending colon mucosa than BYT group and SJT group(P<0.01); SBS group and BYT group had lower renal AQP2 than SJT group(P<0.05 or P<0.01). Conclusion Rat model with spleen-deficiency syndrome has disordered water-electrolyte metabolism and abnormal water transport. The spleen-strengthening recipes, which have the actions of strengthening spleen, strengthening spleen to drain dampness, strengthening spleen to elevate yang, can improve the disorder of water metabolism to some degrees, and SBS has the best effect.

According to the existing Provisions for Drug Registration (SFDA Order No. 28), applications for new drugs of traditional Chinese medicine are divided into two parts: the applications for drug clinical trial and for drug production (including new drug certificate). It will last for about 10 years from the application for drug clinical trial to get approving, and it also remains many problems and the low probability to succeed. From the sight of pharmaceutical review, there are mainly two aspects of regulatory compliance and technical issues, mainly for changes without approval of the competent authorities of the country. For example, sample preparation and approval of clinical trial process are significant changes. Technical problems are reporting incomplete data or information submitted does not comply with the technical requirements for review, such as: production process validation does not provide information, the preparation of samples for clinical trials and field inspection, production information, or the information provided does not meet the technical requirements. This paper summarizes the frequently asked questions and to make recommendations to advise applicants concerned, timely detection of problems, avoid risk, improving the quality and efficiency of the application for registration.
